To all whom it may concern Be it known that I, CARL FREDRIK WENN- BERG, a subject of the King of Sweden and Norway, and a resident of Jonkoping, Sweden, have invented a new and useful Improvement in Steam or other Fluid Pressure Engines, of which the following is aspecification.

Foreign patents have been granted for this invention, as follows: in Norway, No. 1,359, dated May 31, 1889; in Sweden, No. 3,356, dated June 1, 1889; in Denmark, No. 303, dated February 3, 1891; in Germany, No. 52,131, dated June 20, 1889; in England, No. 10,351, dated June 25, 1889; in France, No. 198,911, dated June 13, 1889; in Belgium, No. 86,712, dated June 20, 1889; in Italy,No.26,021, dated September 30, 1889; in Spain, No. 9,772, dated August 23, 1889; in Russia, No. 11,086, dated September 30,1889; in Finland, No. 341, dated July 11, 1889; in Portugal No. 1,575, dated May 23, 1891; in Switzerland, No. 1,571, dated August2,1889; inLuxemburg,No. 1,164., dated August 8, 1889, and in Austria-Hungary, No. 42,011 and 190.34.,305, dated November 30, 1889. I

This invention relates to a partially rotary steam or other fluid pressure engine, and consists of the construction and combination hereinafter described and claimed.

In order to enable my invention to be fully understood I will proceed to describe how it can be carried into practice by reference to the accompanying drawings in which- Figure 1 is a vertical section on the line a;y, Fig. 2. Fig. 2 is a horizontal sectional view of the same, the section being taken through the line wy, Fig. 1. Fig. 3 is a front elevation, partly in section, of the wing or piston of the cylinder. Fig. 4 is aplan partly in section. Fig. 5 is an end view of the same. Fig. 6 is a section through the line .oc-y Fig. 3. Fig. 7 is a section through the line0c-y, Fig. 4. Fig. 8 is a section through the line .z-u, Fig. 4. Fig. 9 is a sectional view of part of the cylinder shaft with a fastening bolt for the wings. strip of packing for the outer surface of. the wings. Fig. 11 is an end view of the same.

Fig. is a side-view of the central Fig. 12 is a section of the same through the line .cc-y, Fig. 10. Fig. 13 is a plan of one of the two outer strips of packing for the wings.- Fig. 14 is a side view of the same. Fig. 15 is a section of the same through the line a:-y,Fig. 13. Fig. 16 is an end view of the same. Fig. 17 is a section of the same through the line 00-1 Fig. 1 1. Fig. 18 is a view of the packing'spring shown in Fig. 3. Fig. 19 is a front View of the side packing strip for the wings. Fig. 20 is a side view; and Fig. 21 is a plan of the same.

The steam cylinder A may be of cylindrical, conical or other suitable shape. It is shown of a cylindrical shape in the drawings and is divided into two chambers a, by partitions a, which chambers by means of steam ports of, one on each side of the partition wall, are in communication with the steam chest B. The cylinder shaft D is placed in the center of the cylinder and works in the usual way in stuffing boxes in the cylinder covers and in the partitions provided with packing pieces a and springs (2 the wings d are dovetailed into the periphery of the said cylinder shaft and held together by diametrically placed bolts (1. The details of the wings are shown in Figs. 2 to 21. They each consist of a triangular shaped hollow casting which both on the upper surface and on the sides is provided with grooves for the reception of packing. The outer surface has three strips of packing, the middle one 11 being at both ends provided with a rectangular projection, which fits into a corresponding recess in the upper end of the piece of packing (i at the ends of the wings, the pieces of packing d are in two parts which are caused to expand longitudinally by means of aspiral spring d. The remaining two strips of packing d on the outer surface of the wings and located one on each side of the strip d are both in two parts and made to expand like the pieces on the end of the wings by means of coiled springs d, all the pieces of packing both at the outer surface and end being provided with springs (1 The steam chest B which through the steam ports a. communicates with the chamber of the cylinder, is bored conical and provided with a corresponding slide or plug which is hollow as best shown in Fig. 1, and open on a part of its conicalsurface as at its largest end, these openings 11 and b respectively serving as an outlet for the exhaust steam. The distributing slide Z2 is provided with two cavities b producing the sliding and closing surfaces 12 and b; b is for closing the steam ports a to the cylinder and b is for covering the steam inlet passages 12. The passages 12 may be two or more in number. The distributing slide is kept tightin the valve chest by the pressure of a spring I)", placed in the valve chest head b the spring I) acting on the slide through a pin 1) and a cross piece I)". The supply of steam admitted into the chest B of the distributing slide through the passages b; from the chest B the steam is, by the movement of the distributing slide Z), alternatel y let into the chambers a of the cylinder above and below the partition wall a through the ports a and at thesame time the exhaust steam is, by the movement of the same slide, alternately let into the exhaust pipe V through the ports a the side openings 1) and the bottom openings Not the said slide.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that What I claim is In a steam or other fluid motor, a cylindrical or other circular shaped chamber formed with partitions and a rock shaft centrally thereof, the partitions and shaft dividing the chamber into compartments, and wings 0r abutments fixed to the shaft, having end packing strips and packing strips fitted in their outer or peripheral faces,the central one of the peripheral packing strips having rectangular projections engaging the end strips, and being spring pressed radially, and the packing, strips at the sides of such central strip being divided and the members spring pressed longitudinally, substantially as described.

In testimony that I claim the foregoing as myinvention I have signed my name, in presence of two Witnesses, this 21st day of August, 1889.
